4 1/2 938 N(938) P11 939 Exact
4 3/2 1232 Ξ”(1232) P33 1232 Exact

6 5/2 2494 Possible higher resonances - Tentative
6 7/2 3180 None - None
7 1/2 1748 N(1880) or Ξ”(1900) ~1880 or ~1900 Tentative
7 3/2 2042 N(2000) or Ξ”(2000) ~2000 Tentative
7 5/2 2532 Possible higher resonances - Tentative
7 7/2 3218 None - None

Notes: Predicted energies are calculated using \( E_{n,J} = E_n + [J(J+1) - \frac{3}{4}] \times 98 \) MeV, where \( E_n = -3390 + 1546n - 116n^2 \) MeV for \( J = \frac{1}{2} \). The total energy includes the proton rest mass (938 MeV) at the ground state (\( n = 4, J = \frac{1}{2} \)). Match quality reflects proximity to measured masses and consistency with quantum numbers (J, parity, etc.). For \( n > 7 \), the quadratic formula predicts decreasing energies (e.g., \( n = 8, E_n = 1554 \) MeV), which may not be physical, so the table is limited to \( n = 4 \) to \( n = 7 \).
